PCT No. PCT/SE96/00890 Sec. 371 Date Dec. 4, 1997 Sec. 102(e) Date Dec. 4, 1997 PCT Filed Jul. 2, 1996 PCT Pub. No. WO97/03244 PCT Pub. Date Jan. 30, 1997A method for cooking chips which are impregnated, in a vessel (3), with liquid in first and second concurrent impregnation zones (A, B), impregnation liquid being supplied, in a mixture with steamed chips, through a feeding system to the first impregnation zone, and liquid for recovery being extracted at a first point (41) at the end of the first impregnation zone, and further liquid being supplied to the second impregnation zone (B). According to the invention, liquid is extracted at a second point (43) at the start of the second impregnation zone (B) and is circulated in an impregnation circulation (44, 45) which empties out at the center of the vessel at a point between the first and second points (41, 43) for extraction of liquid so that a flow of liquid is established from the center of the vessel in a radial direction. The further liquid is supplied to the impregnation circulation for continued impregnation of the chips in the second impregnation zone. |
